SPECIFICATION forming part of Letters Patent No. 631,114, dated August15, 1899:

Application filed J annary 24, 189 9. Serial No. 703,218. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES V. HULSE, a citizen of the United Statesresiding at New York, (Brooklyn,) in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Aliningand Leveling Methods and Devices, of which the following is aspecification.

This invention relates to improvements in type alining and levelingdevices, the main object of the invention being to facilitate thealinement and level adjustment of the type of a type-writer, theinvention being particularly applicable to bar type writers. When soused, the purpose of the invention is to insure accurate adjustment ofthe typebars, so that each type will be brought up in exactly correctposition not only as regards its lateral and longitudinal adjustment ina horizontal plane, but as to the exact coinci dence of the face of thetype with the face of the platen. Any tipping of the type in anydirection from the correct position would prevent such coincidence, andit is therefore necessary to adjust the type by a leveling adjustment aswell as an alining adjustment. My invention relates particularly tomeans for facilitating this leveling adjustment. My improved levelingand alining means is, how ever, capable of other uses in connection withthe adjustment of type. Thus it maybe used to set type-blocks formachines of the centor-guide class in such manner that they are held ina holder in definite relation to the face of the type, so that the edgesor corners of said blocks may be ground off accurately to the properpositions and angles for insuring correct impression.

My invention may also be used in leveling the type on type-wheels oftype-writers of the index Wheel class, as hereinafter described, and ingeneral the invention may be used in the adjustment to any desiredangular position of any face of abody of any kind or in setting a bodyinto conformity with a fixed gage of corresponding form. I have,moreover, found that when the device is thus used it will detect at thesame time any abnormal depressions or elevations on the face of the typeor other body. Thus if the obscuring medium be lighter in color than thetype-face any scratches or pits will show as light lines or spots, whileany raised places will show in corresponding dark outlines. Looked at ina broad sense, therefore, the invention may be regarded as a means forinspecting a surface to ascertain or determine any departure of suchsurface from conformity with a standard or gage surface, whether suchdeparture be due to defects of the configuration of the said face or toangular deviation of such face as a whole.

This invention, in fact, is generally applicable to any case where it isdesired to adjust a body to a given position or to adjust a gage tocorrespond to a given object.

An important feature of my invention is a transparent gage-plate, whichin the side toward the type has a displaceable, reducible, ortranslucent obscuring film or medium for determining whether thetype-face conforms to the face of the gage. For this purpose such mediumis adapted to normally obscure the type, but to permit of the type-facebeing seen or at least brought into evidence either by the penetrationof such medium by the type or by alteration of the position of themedium by the type, or, in the case of a translucent medium, by reasonof the property possessed by such medium of permitting objects to beperceived through same only when in direct contact therewith.

Another feature of my invention relates to forming the leveling-face ofthe gage to coincide orbe identical with the face of the platen. Thuswith the usual cylindrical platen the face of the gage against which thetype is to be placed in leveling is according to my invention made of acylindro segmental shape to represent or correspond to a portion of theface of the platen at the printingpoint. The objectof this is to enablesuch gage-surface to fit or conform to the printingfaces of the types,which in such case are concavely curved to conform to cylindrical faceof the platen. Furthermore, to enable the same gage to adjust itself toboth or all the type of a double-shift or multiple-shift type-writer Iform the face against which the type is alined and leveled with a numberof cylindro-segmental face portions corresponding in shape and positiontothe different working positions of the platen-face.

My invention further relates to means for adjustably supporting thetype-writer frame and the gage and to other details of construction, ashereinafter set forth.

In the accompanying drawings, Figure 1 is apartly-sectional sideelevation of an alining and leveling apparatus embodying my invention,wit-h a type-writing machine shown diagrammatically in the positionassumed in setting the gage. Fig. 2 is a partly-sectional frontelevation of the apparatus shown in Fig. 1. Figs. 3, 4, and 5 arerespectively top, longitudinal, and transverse sections of the gage andits holder. Fig. 6 is a vertical section of my gage adapted to atype-writer of the visible-writing class, where a mirror is required toenable the operator to look through the gage at the type. Fig. '7 showsthe application of a gage comprising one feature of my invention to theleveling of the type on the type-wheel of an index-wheel type-writer.Fig. 8 is a side view of a device wherein my invention is utilized insetting type in proper position in a holder preparatory to dressingsame. Fig. 9 is a side view of the dressing apparatus with type-holderin position for dressing. Fig. 10 shows an auxiliary device formaintaining the type-bars in convenient position for alinement.

Referring to Figs. 1 and 2, I have therein shown my invention applied tothe alinement of a bar type-writer, whose frame is indicated at 1 andone of Whose typo-bars is indicated at 2, 8 being the link and at thekey-lever corresponding to such type-bar. The type-writer in question isassumed to be a double-shift type-writer, the two positions of theplaten being indicated in dotted lines in Fig. 1 at 5 5, and the twotype or characters 6 6 on the type-block 7 are curved and positioned toconform to these two positions of the platen, as usual.

A represents a bed-plate, on which I prefer to support both thetype-writer and the alining devices. On this bed-plate slides a frame B,resting by its slide-rails b on grooved supports'b on bed-plate A, and aframe 0 is mounted by its sliding rails c and grooved supports 0 so asto be movable transversely to the motion of the frame B. Screws Band Oserve to adjust the respective frames B and C in their slides. Thetype-writer is placed on the upper frame O, and by adjustment of theframes B C can be adjusted longitudinally and transversely. On thebed-plate Ais also fixed a standard D, in which is rotatably mounted avertical pivot-post E, which, with its projecting arms 0 6, forms abracket for supporting the gage, such bracket swinging horizontally onits pivot-post E as a center and being held in position over or awayfrom the type-writer, as desired, by a spring-pin (I engaging in one ofthe notches d in the pivot-post. A vertical spindle F is mounted in theouter ends of arms e 6, so as to be movable vertically and rotatablytherein, and has a screw-threaded portion f engaging in a threadedsleeve or nut G, embraced between the upper and lower arms (2 c of thebracket. A sleeve h is interposed between the spindle F and the bearingor bracket-arm e and is splined to said spindle, as indicated at f, andis restrained from vertical movement bya pin it working in annulargroove 71 in said sleeve. This sleeve carries a worm-wheel I, with whichengages a worm 2', provided with handle 7: for manual adjustment. By adjustment of nut G the spindle F may be adjusted vertically, and byadjustment of the worm i the said spindle may be adjusted rotatively ina horizontal plane. This spindle at its lower end is bored to receivethe shank j of the gage-holder J, which is secured therein by aset-screw f The gage-holder J supports the gage K by a gimbal oruniversal joint, preferably of the form shown, the gage being fixed in aframe L, which is pivoted at- Z l on a frame L, piv= oted at Z Z in armsj of the holder-j, the axis Z Z being at right angles to axis Z l, sothat the gage is capable of tilting in any direction. To the gage-frameL is attached an arm M,

engaging by a ball-joint m with an arm M,

provided at its other end with a ball m, fitting in a socket formedpartly in the body of holder J and partly in a collar N, which slides onshank j and is engaged bya nut N, screwing on a threaded portion j ofsaid shankj. \Vhen this nut is screwed upwardly, the ball-joint m isloose, and the arms M M consequently permit free tilting of thegageframe in any direction. By screwing the nut N down tight the ball mand arms M M may be held rigidly, and thus the gage-frame L may be heldto any desired position.

The gage above referred to consists, essentially, of a transparentgage-plate K, preferably formed of glass in one or any desired number ofpieces, the term plate indicating only that it is mechanically anintegral rigid element. This gage-plate is provided with a clear ortransparent portion 8, corresponding to the limits within which the typecharacters are to be alined, and surrounding same-colored or obscuredportions I I, preferably of diiferent colors on different sides,(indicated by diiferenee in the direction of the shade-lines,) so as tomake the respective vertical and horizontal limits more apparent. Thelower surface of this gage-plate, which I term the leveling-surface, isformed with two cylindro-segmental portions 70, whose curvature is thesame as that of the platen of the type-writer to be alined and whoserelative positionsthat is, the distance between their centers ofcurvature-are the same as the relative portions or the distances betweenthe two working portions of the platen, as indicated by dotted lines 5 5in Figs. 1 and 5, and when the gage is set to proper position its curvedsurfaces aforesaid coincide with the positions that would be occupied bythe platen in its two working positions, the platen being, however,removed or swung back out of the way when the gage is put in place. Onthe under side of the gage-plate is provided an obscuring means forpermitting the type to come into full visibility'only when the typefaceis in direct, full, and even contact with the gage-face or with suchobscuring means. This means may consist of a translucent film on thebottom of the glass gage-plate, formed either by grinding the glass toroughen it or by a translucent coating; but I prefer to employ anobscuring means comprising a viscous opaque or translucent paint orpaste, which is displaceable under the pressure of the typeface, so asto allow the type-face to become visible. This paint or paste (indicatedato in Figs. 4 and 5) I prefer to cover with a flexible and reducibleshield or film O of soft rubber, which is held to the frame L by an openclam pframe 19. The rubber being elastic and also reducible ordisplaceable, it permits the typeface to effect the displacement of thepaste, and thus enable the type-face to become visible through the gage,when said type-face is pressed into direct and full contact with therubber and in perfect parallelism with the surface of the gage-plate.The glass gage-plate K is held in its frame L by any suitable bezel orclamp-frame g, and the upper face of the gage is preferably formed as alens or a plurality of lenses to magnify the face of the type as seenthrough same.

The first operation in the use of my alining and leveling device is toset a certain one of the types of the type-writer incorrect printingposition, so that the gage may be set in conformity thereto. The typereferred to is called the master-type and is the'type indicated at 6 6in Fig. 1, being, for example, the type carrying the characters N n. Forthus setting the master-type I use an auxiliary device (shown in Figs. 1and 2).comprising a cross-bar or frame R, in which a vertical rod S isdetachably mounted so as to slide freely, being pressed up by a spring'1', and a set-screw T being provided to enable the rod to be clamped inany desired vertical position. In using this device the type-writerplaten, with its carriage, is first swung back out of the way. The bar Ris inserted within and through the basket or assembly of type-bars, soas to rest on the frame 1 on each side of the machine. The rod S is theninserted in the vertical hole in the center of said bar and themaster-type is placed on the top of said rod S, preferably enlarged, asat s, to form a more secure support. The spring 0" now presses the rod Rand the master-type upwardly, and the platen being brought down on topof the master-type the latter is brought to exact vertical adjustment,its face corresponding or conforming to the platen-face, as indicated inFig. 1. .The rod Ris then locked in position by set-screw T. It will beunderstood that the master-type has already been adjusted to properalinement and also to proper angular position or level, so as to make afull and even impression against the platen, this having been effectedby the usual method of trial impressions, in conjunction with manualadjustment of the type-bar and its support, in a well-known manner.Therefore when the master-type has been set as above described it isonly necessary to bring the gage to conformity and alinement therewithand then to aline and level the remaining type by such gage. To set thegage in this manner, the type-writer platen is removed or swung back outof the way and the gage-supporting bracket is swung around so as tobring the gage-holder over the master-type. The operator then proceedsto adjust the type-writer in horizontal, longitudinal, and transversedirections by means of adj ustingscrews B O and to adjust thegage-holder in I vertical and rotative adjustment by nut G and worm iuntil the gage and master-type are brought into alinement and closeproximity or contact, the nut N being meanwhile maintained loose, so asto allow the gage to adapt itself freely to the face of the type. Inthis operation the gage is watched and when the type comes at any pointin contact with the obscuring medium ,below the gage-plate it will atonce become apparent, any parts, however, of the type-face that remainbelow the proper level being either still invisible or more or lessobscured. By manipulating the gage it is, however, evident that it canbe brought into exact coincidence or conformity with the master-type,inasmuch as they are universally adjustable relatively to one another.At the same time the gage is brought into exact alinement with suchmaster-type by observation of the position of the type characters withinthe clear spaces 8. The difierently-colored boundaries on differentsides of this clear space facilitate the accurate alinement of the type.Havin gth us been correctly alined and leveled, the gage is locked inthat position by screwing tight the clamp-nut N. Themaster-type-supportin g devices may now be removed and then the operatormay proceed to aline and level the other type characters by bringingthem into alinement with and conformity to the gage-plate. In so doingthe type-bars are adjusted in the wellknown manner by bending thetype-bars and adjusting their supports, their condition as to alinementbeing determined by observation of the position of the type relativelyto the differently colored boundaries of the clear-glass space of thegage, and the condition as to leveling being indicated by the extent ordegree of visibility of the type-face through the obscuring-film. Inorder to facilitate the adjustment of the remaining typebars, I preferto employ means for maintaining the type against or in proximity to thegage-plate, so as to avoid the necessity of the operator pressing thecorresponding type-key continuously or repeatedly. For this purpose anadjustable extensible bracket U, (see Fig. 10,) swinging on a standardV, carries at its free end a Weighted rod W, which is adapted to rest onany one of the keys, said rod being movable vertically in the bracket U.This rod may be quickly shifted from key to key, but is held fromaccidental lateral displacement by the slight frictional resistance ofbracket U.

The obscuring medium for the transparent gage-plate may be variouslymodified without departing from the essential feature of myinvention-namely, a medium preventing or obscuring full visibility untilthe type-face is in direct and full contact therewith. Thus fairly goodresults can be obtained with the rubber film alone without the viscousobscuring-film, and, on the other hand, the rubber film may be omitted,so as to allow the type-face to come into direct contact with theviscous film and to penetrate same, so as to become visible when itcomes in contact with the gage-surface, or both these may be omitted andthe lower or leveling surface of the glass gage-plate may be simplygrained or roughened, so that it is translucent, but not transparent. Infact, any obscuring film or medium that is either translucent or ispenetrable, displaceablc, or reducible under the pressure of thetype-face will serve the purpose. As examples of such obscuring media Imay also cite Iceland spar, tourmalin, and similar bodies, which do notpermit visibility except when the object is in direct contact therewith.Such embodiment of my invention is more particularly and specificallyset. forth and claimed in my application Serial No. 723,442, filed July11, 1899. Furthermore, the flexible sheet 0 in Fig. 1 instead of beingrubber may be of a fabric of contrasting color to the coating ofpaintfor example, of black silk, if white paint be used so that normallythis fabric does not appear, but being pressed against the glass by thetype-face it is displayed along the line of the type-face, thus showingcontact of the typeface without such type-face being directly visible.In myapplication Serial No. 723,441, filed July 11, 1899, I havedescribed and claimed an embodiment of my invention involving thisprinciple which is not specifically claimed herein.

In applying my invention to machines wherein the type strike downwardlyor away from the operator in order to give a visible impression it isnecessary to provide a mirror to reflect back to the operator the viewof the type-face as seen through the transparent gage-plate. Such adevice is shown in Fig. 6, where a glass prism K is used as a totalinternal reflector, one face k thereof being used as the alining andleveling face and the other face a being formed as a lens whichtransmits a reflected image of the type-face to the operator in front ofthe machine. 0 represents the rubber obscuring-film, and 7 the type.

Fig. 7 shows the application of my invention to leveling the type of anindex-wheel type-writer. Z represents the type-wheel,

carrying type Z and mounted on a suitable axis, with means, such as afixed perforated disk 11, arm 12 on the type-wheel carrier, and aset-pin 13, to adjust the type-wheel to bring any of its type under thegage. Such gage comprises a lens K, mounted in a suitable support D. Tolevel the type, they, or the bottom of the gage, are coated with aviscous paste or paint, and the body of the type-Wheel is then prickedby a hot pin in the usual manner at points adjacent to the depressedparts of the type, so as to raise such parts, the condition as to leveladjustment being determined, as above described, by the visibility ofthe typeface through the obscuring-film formed by the viscous paint.

An important application of my invention is in the dressing of type forcenter-guide machines. Such type have to be dressed ac-' curately at thesides, ends, and upper corners to fit into the center guide and beproperly alincd and leveled thereby. Fig. 8 shows a device for settingthe type in aholder in proper position for such dressing, such devicecomprising a base 14, a standard 15 thereon, a lever 16, pivoted to saidstandard at 16 and carrying the gage K, and a support 17, slidablc onguides 18 on the base 14 and detachable from said guides. A toggleconnection 19 19 between the lever 16 and the base 14 enables the leverto be raised out of the way or lowered to proper position, in whichposi-' tion it may be locked by an arm 20, pivoted at 15 to the standard15 and engaging by its notch 20 with the hinge-pin 19 of the toggleconnection 19 19. The support 17 carries on a standard 21 a screw-ring22, on which screws a screw-cap 23, between which and the top of ring 22are arranged plates 24 24, embracing a spherical collar 25 on a tube 26.A rod 27 slides vertically in the tube 26 and may be clamped therein bya set-screw 28, said rod being pressed upwardly by a spring 30 andcarrying the type 7 at its top. The gage, which is constructed, as abovedescribed, to conform to the type-surface, the curvature of the gagebeing coincident with the platen-circumference (indicated at 5 in dottedlines) is brought down and locked in position on the type after thesupport 17 has been slid in place, and the screw-cap 23 being loweredthe type is adjusted angularly by the ball-joint 25, horizontally byplates 24 24, sliding on the top of the ring 22, and verticallyandrotatively by the rod 27, sliding in tube 26, the verticaladjustmentbeingeifectedbythespring29. The type having been thus alincdand leveled to the gage, its holder is locked in position by screwingtight the set-screw 28 and the screw cap 23. The support 17 is then slidout of the guides in -base 14 and slid into similar guides 18 on a base31 on the dressing apparatus, (shown in Fig. 9,) on which it is carriedbetween the cutters 32 32 of a suitable milling-cutter, which dressesthe sides and corners thereof in obvious manner.
